In the second pic that is a water stain from me wiping the top down after spilling an ashtray and not seeing that it ran down the side,looks better now. They sound very good. Was using a fisher tube integrated but it made a poping sound so now I'm using a couple of receivers to see what I like (a marantz 2238 and a pioneer 980). Looking to go with a class A SS amp or tubes in the future. Can believe how little power they need. Smaller port or wings seem to be the next step.
